My invention yrelates to dry room tumblers for use in laundries,`and onev objectistoprovide a relatively simple apparatus of this character whereby clothesy and other `washed articles can be dried'm'ore quickly and economically than heretofore. v A furtherobject` is to provide an,v apparatus v of this- (character embodying a plurality Iof individual "receptacles each adapted'to hold kthe ywash `of a family, so thatv clothes `belongin 'to ldiierent vfamilies will not become mixe 1 The invention, broadly "speaking, consists dr ing` chamber- "providedy with ightly inclined, onwhich 'the rotary skids t receptacles are caused to rotate vand fgslowly, `'pursue a path from vend` to end Lof-'said chamber; suitable doors or windows far` ranged adjacent tothe ends of the chamber for' the introduction and removal of thereon'- tainersl; means for heating the air 1in the' chamber; vmeans for circulating 'the hoty airv Y throughout the chamber; and one or more; openin for the escape of lthe moist fair romtechamber. 1

Other features will hereinafter ap ear, and vin order that the invention may be ully understood, reference will now be had' to the Fig. A1 1s a'broken sid elevation ofthe apparatus. v 1 l Fig. 2 is abrokenlongitudinal sectionfof the apparatus, with the ower removed. V' Fig. '3 is a front elevation.` t 'g Fig. .4 is a cross section on line IVe-IV of Fig. 1, with the recap acle in'eleva'tion. I

ig. 5 is a centra section of yone of the receptacles. V

n carrying out the invention, Iemploy a t long -drylng chamber 2, which may rest directly upon the Yfloor ofl the'fbuilding, or upon blocks 4 as shown. The'fchamber 2j cnslsts, preferably, of a "wooden jacket' 6 f1 42'andfitarenormalll I v l'and 48 mounted in slrdewaysand52, re-y the outflow, respectively, otfthe steam Aor other heating agent.
